Error in plot.new() : figure margins too large

This error message usually occurs when the plot size is too large for the current device or when the margins are set too high. To fix this error, you can try the following:

1. Adjust the plot margins using the `par()` function. For example, you can try reducing the margins by running `par(mar=c(2,2,2,2))`.

2. Resize the plot window or device using the `windows()` or `png()` function. For example, you can try setting the plot size to 5 inches by 5 inches by running `png("plot.png", width=5, height=5)`.

3. Use a different plotting function or package that can handle larger plot sizes. For example, you can try using the `ggplot2` package instead of base R plotting functions.

4. Try reducing the amount of data being plotted or simplifying the plot. For example, you can try plotting a subset of the data or using fewer plot elements.
